http://askubuntu.com – So I'm running Ubuntu 12.04.1 on my iMac G5 powerpc64 and I want to add the trash icon to the desktop. How do I do that? Please note, I am NOT using Unity. I tried hitting Alt-F2 and typing gconf-editor but it says that there is no such file or directory. Please help! (HowTos)
